Product 1

HCID 220074251-[2-(2-Hydroxyphenyl)amino-4-pyridyl)-2,3-bis(hydroxymethyl)-6,7-dimethoxynaphthalene

Procedure

1-(2-Bromo-4-pyridyl)-2,3-bis(hydroxymethyl)-6,7-dimethoxynaphthalene and 2-oxobenzoxazolidine are treated in the same manner as Example 6-(2) to give 1-[2-(2-hydroxyphenyl)amino-4-pyridyl)-2,3-bis(hydroxymethyl)-6,7-dimethoxynaphthalene which is a hydrolysis product of 1-[2-(2-oxobenzoxazolidin-3-yl)-4-pyridyl]-2,3-bis(hydroxymethyl)-6,7-dimethoxynaphthalene and listed in Table 6.
